When the target device receives the target data packet, whether the target data packet needs local processing or not can be determined based on the packet receiving port of the target data packet and the data packet processing rule. It can be understood that, if the packet receiving port of the target data packet is the communication port between the target device and the opposite device, the target data packet is a data packet sent by the opposite device and needs to be processed by the local device. If the packet receiving port of the target data packet is other port, whether the packet receiving port needs local processing or not can be determined according to the characteristics of the target data packet and the data packet processing rule.

When a target data packet is received, communication information such as a source IP address and a destination IP address of the target data packet can be extracted, a session identifier of a session to which the target data packet belongs is determined based on the source IP address and the destination IP address, processing equipment corresponding to the session can be determined according to the corresponding relation between the session identifier and the equipment identifier, and then processing equipment of the target data packet in the session is determined.

the judging module is used for determining a packet receiving network port of the target data packet if the target data packet is received, and judging whether the target data packet needs to be processed by the local computer or not based on the packet receiving network port and a data packet processing rule; if not, starting the working process of the adding module;
the adding module is used for adding identification information for identifying the type of the data packet in the target data packet to obtain a forwarding data packet;
a sending module, configured to send the forwarding packet to an opposite-end device, so that the opposite-end device processes the forwarding packet based on the packet type; the target device and the opposite terminal device are two devices in a dual-host hot-standby system, and the dual-host hot-standby system is in a dual-master mode.
9. An electronic device, comprising:
a memory for storing a computer program;
a processor for implementing the steps of the data packet processing method according to any one of claims 1 to 7 when executing the computer program.
10. A computer-readable storage medium, on which a computer program is stored which, when being executed by a processor, carries out the steps of the data packet processing method according to any one of claims 1 to 7.
